Output Relay Tests - Siemens 7SG11 Technical Manual

3.9 Output Relay Tests

This test checks that the output relays are functioning correctly. The output relays should be energised
in turn and the contacts should be checked for correct operation using a continuity tester. The output
relays can be energised in a number of ways. The following is the recommended method :
Assign each output relay in turn to 'Protection Healthy' in the output relay menu. On pressing the
ENTER key the output relay selected will be energised. Check with a continuity tester that the actual
contacts have operated. De-select the output relay and check that the contact returns.
(Assigning the output relays to 'Protection Healthy' ensures that they stay energised until they are de-
selected. Otherwise, if they were assigned to a protection element, they may only be energised for the
minimum output contact time, which is 100ms. This might not be long enough time for a continuity
tester to register.)
Connect the continuity tester between the following terminals to test the output relays :
For E4 case size relays :
Output Relay
Relay 1
Relay 2
Relay 3
Relay 4
Relay 5
Relay 6
Relay 7
For E6 case size relays :
Output Relay
Relay 1
Relay 2
Relay 3
Relay 4
Relay 5
Relay 6
Relay 7
Relay 8
Relay 9
Relay 10
Relay 11
Note : when finished testing the output relays make sure that the 'Protection healthy' is re-assigned to
the correct output relay given in the settings file and that all other relays have been de-selected from
this option.
Record the operation of the Output Relays in Table 2.
